15kw compressor air capacity is about 88 CFM @7bar. So if you need 80 cfm rotary screw compressor, you can choose this one. And this 15 kw compressor is fixed speed type. For this 20 hp industrial screw compressor, the available pressure is 7bar, 8bar, 10 bar and 12bar. Its regular voltage is 380V 50hz three phase. Of course, we can customize it according to your voltages.

This 15 kw screw air compressor is direct drive type. In addition, it has a simple structure and stable quality. The 20hp industrial compressor has many applications, such as metal surface sandblasting, surface painting, foundry, printing machinery, control valves, instruments power, etc.

(1) Reliable quality twin screw airend

The 15 kw compressor uses high precision twin-screw rotors. The volumetric efficiency is as high as 99%. A strong heart determines the excellent performance of the whole machine. It adapts high efficiency direct driving. Besides, our air compressor uses 20000 hours oil seal design. There are with high performance 4pcs SKF bearings.

(2) High power pure copper motor

It uses IP54 class fixed speed motor. It has low revs and high starting torque. Besides, the motor has good stability. With fully enclosed structure, it can prevent strong water jets. Improve motor life. There is no loss in the direct connection structure.

(3) This 15kw compressor is with super filtration system

Intake air filter: high quality filter to remove particles before entering the airend;
Excellent brand oil filter: spin-on oil filter to protect the long lifespan of the airend;
Oil fine separator: effectively reduce metal loss and ensure filtering effect;
Oil and air separation tank: improve the compressed air quality, reduce the exhaust oil content and prevent pipeline blockage.

(4) Microcomputer control system

Easy and friendly human-machine interface. Easy to operate the 80 cfm rotary screw compressor. There are complete automatic protection functions: e.g. automatic fault alarm, fault stop, etc. Besides, it can monitor the data of the air compressor in real time.

(1) Air compressor exhaust pressure

Firstly, it is necessary to determine the working pressure required by the air-use end. Then add an allowance of 1-2 bar. Finally select the pressure of the air compressor. Because there is a pressure loss during the air delivery process. The larger the pipe diameter and the fewer the turning points, the lower the pressure loss. On the contrary, the greater the pressure loss. For example, the 20 hp screw compressor has four pressures for choice. You need to tell the factory which pressure you need.

(2) Air volume flow

First need to know the volume flow of all air equipment. Multiply the total number of flows by 1.2. If the selection is too small, it may cause the air compressor to be unusable. For example, the air compressor may be in a loaded state for a long time. The air capacity of our 15kw compressor is as follow: if you need 8 bar, the air flow is 77 cfm. And if you need 10 bar, the air capacity is 67 cfm.

(3) Tell us the voltage of the 15kw compressor you need

Different voltages, different spare parts and prices. The regular voltage of 20hp screw compressor is 380V 50hz 3-phase. If you need special voltages, the price will be a bit more expensive. And the lead time will be also a bit longer.

Q1: Is this 15 kw air compressor is power frequency or variable frequency type?

A1: It is power frequency type air compressor. There is no inverter.

Q2: What’s the noise of this 80 cfm rotary screw compressor?

A2: The noise is low: 68dB.

Q3: What’s warranty time of your 15kw compressor?

A3: The whole 15 kw compressor has one year warranty time. And the airend warranty time is 2 years.
